Please tell me I'm not alone!

I feel like lately all I do is obsess about my baby's sleep. I google sleep regression and sleep schedules and just hope that what I'm doing isn't damaging him for life. Will he ever sleep properly if I continue to rock him to sleep? If we don't have enough a set routine? Will us moving during his 4 month regression cause lifelong sleep issues? Please tell me I'm not alone and it gets better. I want to just go with the flow but feel like I'm getting neurotic. Lol. I have a very healthy baby who will be 4 months next week and I am very fortunate with how agreeable he is. I just need some solidarity and someone to tell me to stop googling. Lol. I mean...I'm sure my mom never worried about this and I am able to sleep just fine. Is it just part of being a parent during the age of information? Too much access to opinions and 'medical advice'..
